In this paper, a new method of charging and repairing lead-acid batteries is proposed. Firstly, small pulse current is used to activate and protect the batteries in the initial stage; when the current approaches the optimal current curve, the phase constant current charging is used instead, when the voltage is low.
electrolyte in lead-acid batteries and the loss of active substances on the plates. Catholic University of America uses microcontroller to output PWM signal to control switching circuit and generate positive and negative pulses to repair lead-acid batteries . Battery repair technology is a hot topic in recent years.
Major universities and enterprises are striving to find better repair methods, reducing the amount of battery waste. Reducing the waste of resources is an important manifestation of building an environmental friendly society. Therefore, the problem of battery repair has received more and more research. 3.
In the process of charging, a small amount of reverse pulse is given to discharge the battery, which can effectively improve the charging acceptability of the battery. 4.2 Establishment of a new method Firstly, the traditional charging methods are studied.
The battery is not fully charged for the first time, which will lead to the deterioration of the active substance's participation in the chemical reaction, which will reduce the charge and discharge capacity of the lead-acid battery, and will also lead to vulcanization .
the battery is over potential and too much over potential, which will hinder the increase of charging current, slow down the battery chemical reaction speed and reduce the efficiency of charging. In advance of electrolyzed water, a large amount of gas will be generated.

Current flow in batteries?
$begingroup$ Actually a current will flow if you connect a conductor to any voltage, through simple electrostatics. Not noticable at most voltages, but see what happens when you touch a peice of metal to a 100,000kV line, even in a vaccumm with no earth, a sizeable current will flow to bring the metal to the same electrostatic charge.
